I tried LP P6, AK300, N8ii, and owned Sony WM1a, WM1z, iBasso dx300, dx320, 220Max, 3Max, 3MaxTi. To me, with the RS8, I finally reached a point that is undeniably in desktop level performance, and a sound that my ears telling me it eclipse all the others. No more chasing the next dap. Finally full satisfaction. I consider it a well spent investment.
